My mistake. I thought it was a sunpoor fork. But the answers pretty much the same. In your manual for the fork it will give air pressures which depend on your body weight.
If you didnt get a specific manual, and only a general bike one, you can get it online by simply googling X-fusion Mig32 manual.
As i messed up earlier, here it is to save you time.

The maximum air pressure for that fork is 150psi. You should NEVER exceed that or it will go bang and knacker the fork totally.The info is all there, just double check and dont overdo it.
